Abstract: PROBLEM TO BE SOLVED: To restrain the flicker phenomenon caused by the change of current consumption in the case of executing heating output for a fixing device by gradually changing reference voltage for setting output which is used to control a current outputted from a high frequency power source circuit to a coil. SOLUTION: By turning on a switch 44 first, a current flows to an induction heating coil 9. Meanwhile, a current detection circuit 51 transmits a signal to a driving circuit 53 so as to turn off the switch 44 at the time of detecting that the voltage detected by a current detection resistance 55 exceeds the reference voltage 50. The reference voltage 50 is set by a time constant resistance 56 and a time constant capacitor 57 constituting a current consumption rate-of- change control means 70. When a control signal is turned on, the voltage becomes higher and higher through the resistance 56 and the capacitor 57 and is set as the reference voltage 50. Therefore, as the reference voltage 50 becomes higher, the on-time of the switch becomes longer and heating output becomes higher.
